WARNING
Wear riggers gloves for the blade changing operation.
WARNING
Always sharpen blades on a regular basis. Failure to do so
will cause the machine to under perform and will overload
engine and bearings causing machine breakdown. Blades
must not be sharpened beyond the wear mark (see diagram).
Failure to comply with this could result in machine damage,
injury or loss of life.
